본 발명에 따른 차량용 조명의 순차 점등 장치는 도 1 내지 2에 도시된 바와 같이, 직선상으로 연장되게 형성되고, 끝단부에는 빛을 조사하는 광원(11)이 구비된 하우징(10); 및 하우징(10)에 축회전 가능하게 설치되며, 하우징(10)의 연장방향을 따라 직선상으로 연장되게 형성되고 끝단부가 광원(11)에 인접하게 배치되어 광원(11)으로부터 조사된 빛이 입사되며, 둘레면(20a)에는 빛이 출사되는 출사부(21)가 형성되되 일측으로부터 타측으로 둘레면을 따라 연장되게 형성됨으로써, 회전 위치에 따라 빛의 출사 위치가 변화되는 라이트가이드(20);를 포함한다.As shown in FIGS. 1 and 2, the sequential lighting device for vehicle lighting according to the present invention includes a housing 10 formed to extend in a straight line and provided with a light source 11 for irradiating light at an end thereof; and axially rotatably installed in the housing 10 , formed to extend in a straight line along the extension direction of the housing 10 , and having an end disposed adjacent to the light source 11 so that the light irradiated from the light source 11 is incident The circumferential surface 20a is provided with a light emitting portion 21 from which light is emitted, and is formed to extend along the circumferential surface from one side to the other, thereby changing the light emitting position according to the rotational position of the light guide 20; includes

이와 같이, 본 발명은 하우징(10)에 설치되는 광원(11)과 라이트가이드(20)로 구성되며, 광원(11)은 하우징(10)의 끝단부에 설치되고, 라이트가이드(20)는 힌지 구조로 하우징(10)에 회전 가능하게 설치되되 끝단부가 광원(11)에 인접하도록 배치된다.As described above, the present invention is composed of a light source 11 and a light guide 20 installed in the housing 10 , the light source 11 is installed at the end of the housing 10 , and the light guide 20 is a hinge The structure is rotatably installed on the housing 10 , and the end is disposed adjacent to the light source 11 .

상세하게, 광원(11)은 도 3에서 볼 수 있듯이, 기판(11a)에 실장된 LED(11b)로 구성될 수 있으며, LED는 복수개로 구성되고 라이트가이드(20)의 둘레방향을 따라 원형으로 배치되어 라이트가이드(20)에 조사되는 빛이 균등하게 분배되도록 한다.In detail, as shown in FIG. 3 , the light source 11 may be composed of an LED 11b mounted on a substrate 11a , and the LED is composed of a plurality of LEDs in a circular shape along the circumferential direction of the light guide 20 . It is arranged so that the light irradiated to the light guide 20 is evenly distributed.

라이트가이드(20)는 도 4 내지 5에서 볼 수 있듯이, 원통형으로 형성되고, 끝단부가 광원(11)에 인접하게 배치되어 광원(11)에서 조사된 빛이 내부로 입사되며, 내부에 입사된 빛이 전반사되어 길이방향을 따라 이동되고, 둘레면에 형성된 출사부(21)를 통해 빛이 출사될 수 있다. 이렇게, 라이트가이드(20)가 원통형으로 형성됨에 따라 입사된 빛은 내부에서 전반사되어 이동되고, 전반산된 빛이 출사부(21)에 도달시 출사부(21)를 통해 외부로 출사된다. 여기서, 출사부(21)는 라이트가이드(20)의 둘레면에서 외측으로 돌출된 복수의 옵틱으로 이루어질 수 있다. 즉, 라이트가이드(20)에서 옵틱 형상에 의한 표면 형상 변화로 인해, 출사부(21)가 형성된 위치에서는 빛이 전반사되지 않고 투과하여 외부로 출사될 수 있다.As can be seen in FIGS. 4 to 5 , the light guide 20 is formed in a cylindrical shape, and the end is disposed adjacent to the light source 11 so that the light irradiated from the light source 11 is incident therein, and the light incident therein. The total reflection moves along the longitudinal direction, and the light may be emitted through the emitting part 21 formed on the circumferential surface. In this way, as the light guide 20 is formed in a cylindrical shape, the incident light is totally reflected and moved inside, and when the totally reflected light reaches the emission unit 21 , it is emitted to the outside through the emission unit 21 . Here, the emission unit 21 may be formed of a plurality of optics protruding outward from the circumferential surface of the light guide 20 . That is, due to the change in the surface shape of the light guide 20 due to the optic shape, the light is not totally reflected at the position where the emission part 21 is formed, but can be transmitted through and emitted to the outside.

특히, 라이트가이드(20)는 하우징(10)에 회전 가능하게 설치되고, 출사부(21)가 일측으로부터 타측으로 둘레면을 따라 연장되게 배치됨으로써, 회전 위치에 따라 출사부(21)를 통한 빛의 출사 위치가 변화된다. 여기서, 라이트가이드(20)의 회전을 위해, 하우징(10)에는 구동부가 마련될 수 있으며, 구동부의 동작시 발생되는 회전력에 의해 라이트가이드(20)가 회전될 수 있다. 구동부는 모터가될 수 있으며, 캠 구조, 기어 연결 구조 등 다양한 방법으로 라이트가이드(20)가 회전되도록 구성될 수 있다. In particular, the light guide 20 is rotatably installed in the housing 10, and the emitting part 21 is arranged to extend along the circumferential surface from one side to the other, so that the light through the emitting part 21 according to the rotational position. The output position of the is changed. Here, for the rotation of the light guide 20 , a driving unit may be provided in the housing 10 , and the light guide 20 may be rotated by a rotational force generated during operation of the driving unit. The driving unit may be a motor, and the light guide 20 may be rotated in various ways such as a cam structure and a gear connection structure.

이와 같이, 본 발명은 라이트가이드(20)가 하우징(10)에서 회전시, 출사부(21)의 위치가 변화됨에 따라 빛의 출사 위치가 변화되어 순차 점등 효과가 구현된다.As described above, in the present invention, when the light guide 20 rotates in the housing 10 , the position of the light emission is changed as the position of the emission part 21 is changed, so that the sequential lighting effect is realized.

상술한 본 발명에 대해서 구체적으로 설명하면, 도 2에 도시된 바와 같이, 하우징(10)에 장착시 라이트가이드(20)를 덮도록 형성되고, 직선상으로 출광홀(31)이 연장되게 형성되어 라이트가이드(20)로부터 출사되는 빛이 출광홀(31)을 통해 외부로 출사되도록 하는 베젤(30);을 더 포함할 수 있다.Detailed description of the present invention described above, as shown in FIG. 2, is formed to cover the light guide 20 when mounted on the housing 10, and the light exit hole 31 is formed to extend in a straight line. The light guide 20 may further include a bezel 30 configured to allow the light emitted from the light guide 20 to be emitted to the outside through the light exit hole 31 .

여기서, 베젤(30)은 빛이 투과되지 않는 재질로 구성될 수 있으며, 하우징(10)에 장착시 라이트가이드(20)를 덮도록 형성됨에 따라 라이트가이드(20)를 외부 충격으로부터 보호한다. 또한, 베젤(30)에는 라이트가이드(20)의 길이방향을 따라 직선상으로 연장된 출광홀(31)이 형성됨으로써, 라이트가이드(20)로부터 출사되는 빛이 출광홀(31)을 통해 외부로 출사되도록 한다. 즉, 라이트가이드(20)가 회전됨에 따라 출사부(21)가 베젤(30)의 출광홀(31)에 매칭되면, 출사부(21)를 통해 출사되는 빛이 출광홀(31)을 통해 외부로 출사되도록 구성됨으로써, 복수의 출사부(21) 중 출광홀(31)과 매칭되는 위치에서만 빛이 외부로 출사된다.Here, the bezel 30 may be made of a material that does not transmit light, and is formed to cover the light guide 20 when mounted on the housing 10 to protect the light guide 20 from external impact. In addition, a light exit hole 31 extending in a straight line along the longitudinal direction of the light guide 20 is formed in the bezel 30 , so that the light emitted from the light guide 20 is transmitted to the outside through the light exit hole 31 . to be released That is, as the light guide 20 is rotated, when the emitting part 21 matches the emitting hole 31 of the bezel 30 , the light emitted through the emitting part 21 is transmitted through the emitting hole 31 to the outside. By being configured to emit light, only a position matching the light exit hole 31 among the plurality of emission units 21 is emitted to the outside.

이처럼, 라이트가이드(20)는 출사부(21)가 일측으로부터 타측으로 둘레면을 따라 연장되게 형성됨으로써, 라이트가이드(20)의 회전시 복수의 출사부(21)가 출광홀(31)에 순차적으로 매칭됨에 따라 순차 점등 효과가 구현된다.In this way, the light guide 20 is formed so that the emitting part 21 extends from one side to the other side along the circumferential surface, so that when the light guide 20 is rotated, the plurality of emitting parts 21 are sequentially located in the light exit hole 31 . A sequential lighting effect is realized by matching with .

한편, 라이트가이드(20)는 원통형으로 형성되어 광원(11)에서 조사된 빛이 내부에서 전반사되어 길이방향을 따라 이동되고, 둘레면에 형성된 출사부(21)를 통해 빛이 출사될 수 있다.On the other hand, the light guide 20 is formed in a cylindrical shape so that the light irradiated from the light source 11 is totally reflected inside and moves along the longitudinal direction, and the light can be emitted through the emitting part 21 formed on the circumferential surface.

여기서, 라이트가이드(20)는 둘레면의 반사율이 출사부(21)의 반사율보다 높게 이루어질 수 있다. 이에 따라, 라이트가이드(20) 내부로 입사된 빛은 반사율이 높은 둘레면에 반사되어 이동되고, 반사율이 낮은 출사부(21)에서 투과하여 외부로 출사될 수 있다. 즉, 라이트가이드(20)의 둘레면은 미러 효과를 부여하기 위해 고반사 또는 하프미러 증착을 하거나 도장처리하여 반사율이 높아지도록 하고, 출사부(21)에는 표면처리를 하지 않음에 따라 반사율이 낮아 빛이 원활히 투과되도록 할 수 있다.Here, the light guide 20 may have a reflectance of a circumferential surface that is higher than a reflectance of the emission unit 21 . Accordingly, the light incident into the light guide 20 may be reflected and moved on the circumferential surface having a high reflectance, and may be transmitted through the light emitting unit 21 having a low reflectance and be emitted to the outside. That is, the circumferential surface of the light guide 20 is highly reflective or half-mirror deposited or painted to increase the reflectance in order to impart a mirror effect. Light can be transmitted smoothly.

또한, 도 6 내지 7에 도시된 바와 같이, 라이트가이드(20)는 둘레면에 미세 노치(22)가 형성되어 광원(11)에서 조사된 빛이 내부에서 전반사되도록 할 수 있다. 즉, 라이트가이드(20)의 둘레면은 미세 노치(22)를 가지도록 형성됨에 따라, 라이트가이드(20) 내부로 입사된 빛이 노치 형상에 의해 빛이 사방으로 확산되면서 라이트가이드(20) 내부를 원활히 이동할 수 있다. In addition, as shown in FIGS. 6 to 7 , the light guide 20 may have a fine notch 22 formed on the circumferential surface so that the light irradiated from the light source 11 is totally reflected inside. That is, as the circumferential surface of the light guide 20 is formed to have the fine notch 22 , the light incident into the light guide 20 is diffused in all directions by the notch shape, and the light guide 20 inside can move smoothly.

상술한 라이트가이드(20)의 출사부(21)와 미세 노치(22)는 요구하는 빛의 광분포에 따라 크기 및 형상이 변경될 수 있다.The size and shape of the emitting part 21 and the fine notch 22 of the above-described light guide 20 may be changed according to the required light distribution.

한편, 일실시예로서, 출사부(21)는 복수의 옵틱이 일측으로부터 타측으로 회전방향을 따라 나선형으로 배열될 수 있다. 즉, 라이트가이드(20)에서 출사부(21)는 빛이 투사되는 부분으로, 일측에서 타측으로 회전방향을 따라 나선형으로 배열됨에 따라, 라이트가이드(20)의 회전시 빛이 출사되는 방향으로 출사부(21)의 위치가 순차적으로 변동됨에 따른 순차 점등 효과가 구현될 수 있다.Meanwhile, as an embodiment, in the emission unit 21 , a plurality of optics may be spirally arranged along the rotational direction from one side to the other. That is, in the light guide 20 , the emitting part 21 is a portion on which light is projected, and as it is spirally arranged along the rotational direction from one side to the other, it is emitted in the direction in which the light is emitted when the light guide 20 rotates. A sequential lighting effect may be realized as the position of the unit 21 is sequentially changed.

이는, 도 8에 도시된 바와 같이, 라이트가이드(20)를 평면상으로 펼쳤다고 가정하였을 때, 복수의 출사부(21)가 일측에서 타측으로 대각방향으로 연장되는 배열을 이룬다. 이로 인해, 라이트가이드(20)는 원통형 형상을 이룰 경우, 출사부(21)가 일측으로부터 타측으로 나선형으로 배열되는 형태를 이룸으로써, 라이트가이드(20)의 회전시 순차 점등 효과가 구현될 수 있다.This is, as shown in FIG. 8 , assuming that the light guide 20 is spread out on a plane, the plurality of emitting units 21 are arranged to extend diagonally from one side to the other. For this reason, when the light guide 20 has a cylindrical shape, the emission part 21 is spirally arranged from one side to the other side, so that a sequential lighting effect can be realized when the light guide 20 is rotated. .

또한, 출사부(21)는 복수의 옵틱이 일측으로부터 타측으로 회전방향을 따라 나선형으로 배열된 순차점등구간(21a)과, 복수의 옵틱이 순차점등구간(21a)의 타측에 인접하게 위치되며 직선상으로 배열된 전체점등구간(21b)으로 이루어질 수 있다.In addition, the emission unit 21 includes a sequential lighting section 21a in which a plurality of optics are spirally arranged along the rotational direction from one side to the other side, and the plurality of optics are located adjacent to the other side of the sequential lighting section 21a and are straight It may be composed of the entire lighting section (21b) arranged vertically.

도 8에서 볼 수 있듯이, 라이트가이드(20)에서 출사부(21)의 배열 형태는 순차점등구간(21a)과 전체점등구간(21b)을 이룸으로써, 라이트가이드(20)의 회전 위치에 따라 미점등, 순차점등, 완전 점등을 구현할 수 있다.As can be seen in FIG. 8 , the arrangement form of the emission part 21 in the light guide 20 forms a sequential lighting section 21a and a full lighting section 21b, so that the light guide 20 is rotated according to the rotational position. Light, sequential lighting, and full lighting can be implemented.

도 9를 참고하여 보면, 도면을 바라보는 방향으로 빛이 출사되어야 한다고 가정하였을 때, 라이트가이드(20)가 초기 미회전 상태에서는 출사부(21)가 출사방향으로 매칭되지 않음에 따라 미점등 상태가 된다.Referring to FIG. 9 , assuming that light should be emitted in the direction facing the drawing, in the initial non-rotated state of the light guide 20, the emission unit 21 does not match in the emission direction, so the light is not lit. becomes

이후, 라이트가이드(20)의 회전시, 라이트가이드(20)의 회전각도가 40°에서 240°까지 회전됨에 따라 출사부(21)의 순차점등구간(21a)이 출사방향에 매칭된다. 이렇게, 출사부(21)가 출사방향으로 매칭되는 위치가 변환됨으로써, 조명 패턴은 라이트가이드(20)의 회전 위치에 따라 순차 점등이 구현되다.Then, when the light guide 20 is rotated, as the rotation angle of the light guide 20 is rotated from 40° to 240°, the sequential lighting section 21a of the emission unit 21 matches the emission direction. In this way, by changing the position at which the emission unit 21 matches the emission direction, the lighting pattern is sequentially lit according to the rotational position of the light guide 20 .

한편, 라이트가이드(20)가 280°회전된 위치에서는 출사부(21)의 전체점등구간(21b)이 출사방향에 매칭된다. 이로 인해, 라이트가이드(20)의 모든 영역에서 빛이 출사됨에 따라 완전 점등이 구현된다.On the other hand, in the position where the light guide 20 is rotated by 280°, the entire lighting section 21b of the emission unit 21 matches the emission direction. Due to this, full lighting is realized as light is emitted from all areas of the light guide 20 .

한편, 다른 실시예로서, 도 10 내지 12에 도시된 바와 같이, 출사부(21)는 일측으로부터 타측으로 갈수록 복수의 옵틱이 점차 증대되도록 배열될 수 있다.Meanwhile, as another embodiment, as shown in FIGS. 10 to 12 , the emission unit 21 may be arranged such that the plurality of optics gradually increases from one side to the other.

즉, 출사부(21)는 라이트가이드(20)의 일측에서 타측으로 갈수록 복수의 옵틱이 점차 증대되도록 배열됨에 따라, 라이트가이드(20)의 회전시 빛이 출사되는 방향으로 출사부(21)의 면적이 점차 증대됨에 따른 순차 점등 효과가 구현될 수 있다.That is, as the emitting unit 21 is arranged such that the plurality of optics gradually increase from one side of the light guide 20 to the other, the light guide 20 rotates in the direction in which light is emitted. A sequential lighting effect may be realized as the area is gradually increased.

이는, 도 11에 도시된 바와 같이, 라이트가이드(20)를 평면상으로 펼쳤다고 가정하였을 때, 복수의 옵틱이 일측에서 타측으로 대각방향으로 점차 증대되는 배열을 이룬다. 이로 인해, 라이트가이드(20)는 원통형 형상을 이룰 경우, 둘레면에서 출사부(21)가 일측으로부터 타측으로 점차 증대되는 형태로 구성됨으로써, 라이트가이드(20)의 회전시 순차 점등 효과가 구현될 수 있다.As shown in FIG. 11 , assuming that the light guide 20 is spread out on a plane, a plurality of optics form an arrangement in which the plurality of optics are gradually increased in a diagonal direction from one side to the other. For this reason, when the light guide 20 has a cylindrical shape, the emitting part 21 is gradually increased from one side to the other on the circumferential surface, so that the sequential lighting effect is realized when the light guide 20 is rotated. can

여기서, 출사부(21)는 일측으로부터 타측으로 갈수록 복수의 옵틱이 점차 증대되어 최종적으로 라이트가이드(20)의 일측에서 타측까지 복수의 옵틱이 채워질 수 있다. 이로 인해, 조명은 라이트가이드(20)의 회전 위치에 따라 미점등, 순차점등, 완전 점등이 구현된다.Here, the plurality of optics may gradually increase from one side to the other side of the emission unit 21 , and finally the plurality of optics may be filled from one side to the other side of the light guide 20 . Due to this, the lighting is implemented in non-lighting, sequential lighting, and full lighting according to the rotational position of the light guide 20 .

도 12에 볼 수 있듯이, 라이트가이드(20)가 초기 미회전 상태에서는 출사부(21)가 출사방향으로 매칭되지 않음에 따라 미점등 상태가 된다.As can be seen in FIG. 12 , in the initial non-rotation state of the light guide 20, the light guide 20 is in a non-lighting state as the emission unit 21 does not match in the emission direction.

이후, 라이트가이드(20)의 회전시, 라이트가이드(20)의 회전각도가 40°에서 240°까지 회전됨에 따라 출사부(21)의 옵틱이 점점 증대된다. 이렇게, 출사부(21)가 출사방향으로 매칭되는 면적이 서서히 증대됨으로써, 조명 패턴은 라이트가이드(20)의 회전 위치에 따라 순차 점등이 구현되다.Thereafter, when the light guide 20 is rotated, the optics of the emission unit 21 are gradually increased as the rotation angle of the light guide 20 is rotated from 40° to 240°. In this way, as the area in which the emission part 21 matches the emission direction is gradually increased, the lighting pattern is sequentially lit according to the rotational position of the light guide 20 .

한편, 라이트가이드(20)가 280°회전된 위치에서는 출사부(21)의 모든 면적이 출사 방향에 매칭됨으로써, 라이트가이드(20)의 모든 영역에서 빛이 출사됨에 따라 완전 점등이 구현된다.On the other hand, at the position where the light guide 20 is rotated by 280°, all areas of the emission unit 21 match the emission direction, so that full lighting is realized as light is emitted from all areas of the light guide 20 .

한편, 하우징(10)에서 광원(11)은 라이트가이드(20)의 타측에 위치될 수 있다. 즉, 라이트가이드(20)에서 출사부(21)는 일측으로부터 타측으로 연장되는 형태를 가지는바, 광원(11)이 라이트가이드(20)의 일측에 위치될 경우 라이트가이드(20)의 일측에 빛이 과집중되어 광량이 불균형하게 된다. Meanwhile, in the housing 10 , the light source 11 may be located on the other side of the light guide 20 . That is, in the light guide 20 , the emission part 21 has a shape extending from one side to the other side. This over-concentration causes the amount of light to become unbalanced.

따라서, 광원(11)의 경우 라이트가이드(20)의 타측에 배치하여, 조명의 순차 점등시 출사부(21)를 통해 출사되는 빛이 유사 광량을 유지하여 점등 필링이 향상되도록 한다.Therefore, in the case of the light source 11, it is disposed on the other side of the light guide 20, so that the light emitted through the emission unit 21 when the lighting is sequentially turned on maintains a similar amount of light to improve the lighting feeling.

한편, 하우징(10)에는 라이트가이드(20)에서 출사되는 빛이 외부로 투영되도록 하는 투영렌즈(40);를 더 포함하고, 투영렌즈(40)는 하우징(10)의 연장방향을 따라 직선상으로 연장되되 빛의 출사방향으로 돌출되는 길이가 점차 짧아지거나 또는 길어지게 형성될 수 있다.On the other hand, the housing 10 further includes a projection lens 40 for projecting the light emitted from the light guide 20 to the outside, and the projection lens 40 has a linear shape along the extension direction of the housing 10 . It may be formed to be extended to a length that protrudes in the light emission direction becomes gradually shorter or longer.

도 1에서 볼 수 있듯이, 투영렌즈(40)는 직선상으로 연장되게 형성되고, 빛이 출사되는 방향으로 돌출되는 길이가 일측에서 타측으로 점차 짧아지도록 이루어질 수 있다. 이처럼, 투영렌즈(40)는 곡면을 가지도록 형성됨에 따라 3차원 형상이 구현될 수 있다. 또한, 라이트가이드(20)는 출사부(21)가 일측으로부터 타측으로 연장됨에 따라 빛 분배 효율도 향상된다.As can be seen in FIG. 1 , the projection lens 40 may be formed to extend in a straight line, and a length protruding in a direction in which light is emitted may be gradually shortened from one side to the other. As such, as the projection lens 40 is formed to have a curved surface, a three-dimensional shape may be implemented. Also, as the light guide 20 extends from one side to the other, the light distribution efficiency of the light guide 20 is improved.
